Comedian Robert Klein has a routine where he grabs a consumer fruit drink that claims “contains 10% fruit juice,” and asks: “What about the other 90 percent?”
And the graduating class of Harvard MBAs last week had a special new code, A Promise to Be Ethical in an Era of Immorality that 20% of the graduating MBAs signed. The New York Times reported:

Nearly 20 percent of the graduating class have signed “The M.B.A. Oath,” a voluntary student-led pledge that the goal of a business manager is to “serve the greater good.” It promises that Harvard M.B.A.’s will act responsibly, ethically and refrain from advancing their “own narrow ambitions” at the expense of others.

And I can’t help asking: what about the other 80%?
